Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft’s kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology.
“All of us have a responsibility to protect our home planet. After all, it’s the only one we have,” said NASA Administrator Bill Nelson. “This mission shows that NASA is trying to be ready for whatever the universe throws at us. NASA has proven we are serious as a defender of the planet. This is a watershed moment for planetary defense and all of humanity, demonstrating commitment from NASA’s exceptional team and partners from around the world.”
Prior to DART’s impact, it took Dimorphos 11 hours and 55 minutes to orbit its larger parent asteroid, Didymos. Since DART’s intentional collision with Dimorphos on Sept. 26, astronomers have been using telescopes on Earth to measure how much that time has changed. Now, the investigation team has confirmed the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. This measurement has a margin of uncertainty of approximately plus or minus 2 minutes.
Before its encounter, NASA had defined a minimum successful orbit period change of Dimorphos as change of 73 seconds or more. This early data show DART surpassed this minimum benchmark by more than 25 times.
“This result is one important step toward understanding the full effect of DART’s impact with its target asteroid” said Lori Glaze, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “As new data come in each day, astronomers will be able to better assess whether, and how, a mission like DART could be used in the future to help protect Earth from a collision with an asteroid if we ever discover one headed our way.”
The investigation team is still acquiring data with ground-based observatories around the world – as well as with radar facilities at NASA Jet Propulsion Laboratory’s Goldstone planetary radar in California and the National Science Foundation’s Green Bank Observatory in West Virginia. They are updating the period measurement with frequent observations to improve its precision.
Focus now is shifting toward measuring the efficiency of momentum transfer from DART’s roughly 14,000-mile (22,530-kilometer) per hour collision with its target. This includes further analysis of the “ejecta” – the many tons of asteroidal rock displaced and launched into space by the impact. The recoil from this blast of debris substantially enhanced DART’s push against Dimorphos – a little like a jet of air streaming out of a balloon sends the balloon in the opposite direction.
To successfully understand the effect of the recoil from the ejecta, more information on of the asteroid’s physical properties, such as the characteristics of its surface, and how strong or weak it is, is needed. These issues are still being investigated.
“DART has given us some fascinating data about both asteroid properties and the effectiveness of a kinetic impactor as a planetary defense technology,” said Nancy Chabot, the DART coordination lead from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. “The DART team is continuing to work on this rich dataset to fully understand this first planetary defense test of asteroid deflection.”
For this analysis, astronomers will continue to study imagery of Dimorphos from DART’s terminal approach and from the Light Italian CubeSat for Imaging of Asteroids (LICIACube), provided by the Italian Space Agency, to approximate the asteroid’s mass and shape. Roughly four years from now, the European Space Agency’s Hera project is also planned to conduct detailed surveys of both Dimorphos and Didymos, with a particular focus on the crater left by DART’s collision and a precise measurement of Dimorphos’ mass.
Johns Hopkins APL built and operated the DART spacecraft and manages the DART mission for NASA’s Planetary Defense Coordination Office as a project of the agency’s Planetary Missions Program Office. Telescopic facilities contributing to the observations used by the DART team to determine this result include: Goldstone, Green Bank Observatory, Swope Telescope at the Las Campanas Observatory in Chile, the Danish Telescope at the La Silla Observatory in Chile, and the Las Cumbres Observatory global telescope network facilities in Chile and in South Africa.
Neither Dimorphos nor Didymos poses any hazard to Earth before or after DART’s controlled collision with Dimorphos.

Artemis II crew brought a human eye and storytelling vision to the photos they took on their mission
Artemis II crew: Artemis II’s astronaut photos show how human perspective and storytelling make space imagery feel authentic—especially in an era of AI-generated visuals.
Christye Sisson, Rochester Institute of Technology
In early April 2026, the Artemis II mission captivated me and millions of people watching from across the world. The crew’s courage, skill and infectious wonder served as tangible proof of human persistence and technological achievement, all against the mysterious backdrop of space.
People back on Earth got to witness the mission through remarkable photos of space captured by astronauts. Images created and shared by astronauts underscore how photography builds a powerful, authentic connection that goes beyond what technology alone can capture.
As a photographer and the director of the Rochester Institute of Technology’s School of Photographic Arts and Sciences, I am especially drawn to how these photographs have been at the center of the public’s collective experience of this mission.
In an era when image authenticity is often questioned and with the capabilities of autonomous, AI-driven imaging, NASA’s choice to train astronauts in photography has placed meaning over convenience and prioritized their human perspectives and creativity.
Capturing space from the crew’s perspective
Photography was not originally placed as a high priority in NASA’s Apollo era. The astronauts only took photographs if they had the chance and all their other tasks were complete.
Thanks largely in part to public response to those images from Apollo, including “Earthrise” and the “Blue Marble” being widely credited for helping catalyze the modern environmental movement, NASA shifted its approach to utilize photography to help capture the public’s imagination by training their astronauts in photographic practices.
The Artemis II mission’s photographs have helped cut through the increasing volume of artificially generated images circulating on social media. NASA’s social media releases of the crew’s photographs have garnered thousands of shares and comments.
This excitement could be explained by the novelty of photos from space, but these images also distinguish themselves as products of astronauts experiencing these sights and interpreting them through their photographs. These differences require an important distinction around where technology ends and humanity begins.
Human perspective versus AI tools
Photography has long integrated AI-powered software and data-driven tools in a variety of ways: to process raw images, fill in missing color information, drive precise focus and guide image editing, among others. These modern technological assists help human photographers realize their vision.
Artificial intelligence is also increasingly capable of operating machinery competently and autonomously, from cars to drones and cameras.
And AI can generate convincing, realistic images and videos from nothing more than a text prompt, using readily available tools.
Researchers train AI to mimic patterns informed by millions of sample images, and the algorithm can then either take or create a photograph based on what it predicts would be the most likely version of a successful, believable image.
Human-created photos are rooted in direct observation, intent and lived experience, while AI images – or choices made by AI-driven tools – are not. While both can produce compelling and believable visuals, the human photographs carry emotional power because the photographer is drawing from their experiences and perspective in that moment to tell an authentic story.
Artemis II photographs resonate, not only because they are historic, but because they reflect the deliberate choices and intent of a human being in that specific moment and context. The exposure, camera setting, lens choice and composition are all dictated by the astronaut’s vision, skill, perspective and experience. Each image is unique in comparison with the others. These choices give the images narrative power, anchoring them in human perspective.
Images to tell a story
Photographers choose what to include in the final version of their image to tell a story. In the Artemis II images, this human perspective comes out. In the “Earthset” photo, you see a striking juxtaposition of the Moon’s monochromatic, textured surface in the foreground against a slivered, bright Earth.
The choice to include both in the frame contrasts these objects literally and figuratively, inviting comparison. It creates a narrative where Earth is contrasted against the Moon – life is contrasted against the absence of it.
Another photo shows the nightside of the whole Earth, featuring the Sun’s halo, auroras and city lights. The choice to include the subtle framing of the window of the capsule in the lower left corner reminds the viewer where and how this image was captured: by a human, inside a capsule, hurtling through space. That detail grounds the photograph in the human perspective.
Both photos are reminiscent of Earthrise and the Blue Marble. These past images hold a place in the global collective consciousness, shaped by a shared historical moment.
The Artemis II photographs are anchored in this collective moment of lived human experience, yet also shaped by each astronaut’s viewpoint. The crew’s unique perspectives exemplify photography’s transformative power by inviting viewers to engage emotionally and intellectually with their journey. These photographs share the astronauts’ awe and wonder and affirm the value of human creativity and its ability to connect us in a captured moment.

Seeing an eclipse from Earth is awe‑inspiring – for astronauts seeing one from space, the scene was even more grand
Discover the stunning eclipse seen by Artemis II astronauts during their 2026 Moon mission. A truly extraordinary spectacle awaits.
Deana L. Weibel, Grand Valley State University
The astronauts on Artemis II’s trip to the Moon in April 2026 didn’t just have an amazing journey through space. They also saw something extraordinary. They were the first humans to see a total solar eclipse from space.
A solar eclipse happens when the Moon moves in front of the Sun. In a total eclipse, the Sun’s central disc is covered completely.
From Earth, the circle of the Sun is about the same size as the circle of the Moon. With the bright circle blocked, you can see the undulating rays of the Sun’s corona, or outer atmosphere, that are normally too dim to be observed.
I’m a cultural anthropologist who studies awe-inspiring aspects of space exploration. I have been lucky enough to have seen two total solar eclipses. The first one was in Nebraska in 2017, the second in Indiana in 2024.
During my second total eclipse, the period of totality – that short span when you can remove your protective glasses and look directly at the eclipse – lasted close to 4 minutes. I saw waves of diffuse light snaking around an ink-black hole in the sky. It looked very wrong – almost alien.
On Aug. 12, 2026, there will be another total solar eclipse, visible only from Greenland, Iceland, Spain and the Balearic Islands of the Mediterranean. Some fortunate viewers in Spain and nearby islands may see the eclipse just before sunset, low on the horizon. The Moon illusion, a phenomenon where the Moon looks bigger when it’s near the horizon, might make this eclipse look unusually large.
Unusual eclipse perspectives
Astronauts will occasionally also have less common eclipse experiences. I interviewed one I call by the pseudonym “Jackie” in my research about astronauts’ experiences of awe. She was part of an astronaut training group that did a flight exercise during a total solar eclipse.
Jackie and her squad flew their jets in the shadow of the Moon. This lengthened their time in totality because they could follow and stay within the shadow. Jackie was most impressed with how the Sun’s corona seemed to shift and ripple.
“It’s not static … it’s alive,” she told me.
On April 6, 2026, the astronauts of NASA’s Artemis II mission saw another kind of unusual eclipse as they flew around the Moon. At one point during their flight, the Moon and the spacecraft aligned so that the Moon was directly between them and the Sun, blocking the Sun’s disk in a way that looks very different from what we see on Earth.
Astronaut Victor Glover said it felt like they “just went sci-fi.” https://www.youtube.com/embed/YLjPci5bo1k?wmode=transparent&start=0 ‘An impressive sight’: The Artemis II crew were the first humans to observe a solar eclipse from near the Moon.
The astronauts were so close to the Moon that the Moon looked bigger than the Sun and hid more of its bright circle. Earth was also in view, and sunlight reflected from the Earth onto the Moon in a phenomenon NASA calls “earthshine.” This dim light is very similar to the moonlight that shines on the Earth at night.
Imagine the Sun hidden behind the Moon, creating a hazy halo around the Moon’s edges. At the same time, faint light reflected from Earth softly illuminates the Moon, revealing mountains and craters in a dim twilight. Now imagine this striking scene lasting 54 minutes.
This sight was, without a doubt, one of the most unusual eclipses ever seen by human eyes.
Although Artemis’ astronauts are trained to think scientifically, this experience propelled them into a state of awe. They talked openly about how their brains were “not processing” what they observed. While NASA kept them busy with a variety of tasks, the sound of emotion and excitement in their voices as they broadcast live from their lunar flyby was unmistakable.
The psychology of awe
Researchers have studied the effects of awe on the human brain, including awe felt during solar eclipses. Moments of wonder like these can transform how you feel and even how you think, making you more thoughtful and open-minded.
In my own work I’ve found these experiences can change how astronauts understand their own place in the universe.
One astronaut said she gained an awareness of the fragility of our planet that now shapes everything she does, while another described becoming more curious after returning to Earth. A third said the awe he experienced in lunar orbit changed his understanding of time and infinity.
Space travel creates many opportunities for awe, but a solar eclipse from behind the Moon, as Mission Commander Reid Wiseman put it, required “20 new superlatives.”
It’s an experience most of the earthbound eclipse-chasers heading to Greenland or Iceland or Spain this summer will only dream about. Whether eclipses happen in space or on Earth, though, close encounters with the grandeur of our universe can make you feel profoundly human.

Boom Supersonic Update 2026: Overture Progress, XB-1 Milestones, and What’s Next
Boom Supersonic’s 2026 update: XB-1 test success, Overture production timeline, funding progress, and the challenges facing the return of commercial supersonic travel.
By STM Daily News Staff
The race to bring back commercial supersonic travel is accelerating once again, led by Boom Supersonic, a Colorado-based aerospace company aiming to succeed where Concorde left off. As of 2026, the company has achieved meaningful technical milestones—but still faces significant financial, regulatory, and industrial hurdles.
Here’s a comprehensive look at where Boom stands today, and what it means for the future of high-speed air travel.
XB-1 Demonstrator Completes Historic Test Program
Boom’s experimental aircraft, the XB-1, has successfully completed its flight test campaign, marking a critical step toward validating the company’s supersonic technology.
- Achieved multiple supersonic flights in 2025
- Demonstrated aerodynamic stability and performance
- Tested “boomless cruise” capabilities to reduce sonic disturbances
The XB-1 program served as a scaled demonstrator for the company’s flagship commercial jet, proving that modern materials, software, and engine integration can support efficient supersonic flight.
With testing complete, the aircraft is expected to be preserved as a prototype, representing a turning point in private-sector aerospace innovation.
Overture: Boom’s Commercial Supersonic Jet
The centerpiece of Boom’s vision is the Overture, a next-generation supersonic passenger aircraft designed to carry between 60 and 80 passengers at speeds approaching Mach 1.7.
Current projected timeline:
- Prototype rollout: Targeted for 2026
- First flight: Expected around 2027
- Commercial service entry: Late 2020s (estimated 2029–2030)
Unlike Concorde, which catered primarily to elite travelers, Boom aims to position Overture with business-class pricing, potentially expanding access to faster global travel.
The aircraft is also being designed with sustainability in mind, including compatibility with sustainable aviation fuel (SAF).
Funding and Financial Momentum
In recent developments, Boom Supersonic secured an additional $100 million in funding, reinforcing investor confidence in the company’s long-term vision.
However, building a supersonic passenger aircraft remains one of the most capital-intensive challenges in aviation. Continued fundraising and strategic partnerships will be essential as the company moves from prototype to production.
Boomless Cruise: A Potential Game-Changer
One of Boom’s most significant innovations is its focus on “boomless cruise,” a method of flying supersonically without producing an audible sonic boom on the ground.
If proven viable at scale, this technology could influence regulatory changes—particularly in the United States, where overland supersonic flight is currently restricted.
The ability to fly faster-than-sound over land would unlock major domestic routes, dramatically reducing travel times between cities like New York and Los Angeles.
Manufacturing Challenges and Delays
Despite technical progress, Boom’s manufacturing ambitions face uncertainty. A planned production facility in North Carolina has experienced delays, raising questions about when large-scale assembly will begin.
Scaling production from prototype to commercial aircraft remains one of the most difficult phases of any aerospace program, requiring supply chain coordination, workforce development, and regulatory alignment.
Industry Skepticism Remains
While Boom has secured interest from major airlines, skepticism persists within the aviation industry.
Key concerns include:
- Certification complexity and regulatory approval timelines
- Operational costs versus ticket pricing
- Long-term demand for supersonic travel
Even airline executives have expressed cautious optimism, with some suggesting the project’s success remains uncertain.
The Bigger Picture: A Defining Decade for Supersonic Travel
Boom Supersonic has moved beyond concept and into real-world testing, demonstrating that modern supersonic flight is technically achievable.
However, the next phase—bringing Overture to market—will determine whether supersonic passenger travel becomes a viable industry once again or remains an ambitious experiment.
If successful, Boom could redefine global travel times. If not, it will join a long list of bold aerospace ventures that struggled to overcome economic reality.
